DUAL POLARIZED LOG PERIODIC ANTENNA

Design Features : The LPDP-20-500 dual polarized log periodic antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy. The LPDP-20-500 dual polarized log periodic antenna is designed to provide wideband directional transmission/reception of horizontal and vertical radio signals from 20-500 MHz bands. The extra spacers are used between the support booms to improve mechanical durability of antenna. The specially designed mounting arrangement results in fast installation. This dual polarized log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its capability of receiving/transmitting both the E & H polarized signals simultaneously. This high gain cross elements LP antenna provides greater than 7 dBi gain over the 95% of the 20-500 MHz band as the LPDA does not use loading technique to reduce the overall size of array.

Constructions : The LPDP-20-500 assembled log periodic antennas outer-most dimensions are 6 meters (20 feet) long and 7.5 meters (24.5 feet) width & height. The antenna has foldable elements, the longest of which is 3.75 meters. All elements are supplied in two segments for easy of shipping and handling. The complete antenna can be assembled within 10 minutes by two operators with simple hand tools. The elements are attached via a fast deployment self-locking device at points along the boom. The antenna is also supplied with powder coating finish to protect the antenna further from severe environmental conditions. The log periodic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. All the screws, nuts and bolts of log periodic dipole antenna are made of type 316 marine grade stainless steel.
